Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mackerel
Forms the body of the dish, becoming firm and flaky once cooked and preserved.
Coarse sea salt
Draws out moisture and seasons the fish, helping to preserve it.
Vinegar
Adds acidity that helps preserve the fish and gives it a sharp, tangy flavour.
Salad oil or melted suet
Forms a fat layer over the fish that limits contact with air, helping it keep longer.

The step that matters

Pouring the vinegar over the fish. The vinegar must fully cover the fish so that its acidity reaches every piece. Exposed fish can spoil, since acid and a sealed layer of fat together slow microbial growth.

Swap the mace

How well each one fits the dish's main ingredients (pepper, clove, nutmeg, vinegar):

  1. Allspicefits better
  2. Cinnamonfits better
  3. Cardamomfits better
  4. Macethe original

Fit is the average pairing score against pepper, clove, nutmeg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
